From 82b77505f9420f11d614c2ae0f74153ca4ee3cb5 Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Tue, 2 May 2023 09:48:50 +0200 Subject: cooker updates spilling all over the place Only tangentially related: - make seitan C99 again, so that I can build cooker without warnings - make Makefiles make use of the usual conventions about assigning directory paths in variables, drop numbers.h as requirement for cooker and make it convenient to run stand-alone Makefiles - fix up nr_syscalls.sh to be POSIX, otherwise it will give syntax errors on my system - define a single, common way to refer to offsets in gluten, and functions to use those offsets in a safe way. Immediates are gone: cooker will write any bit of "data" to the read-only section - call const what has to be const - define on-disk layout for gluten - add OP_NR (to check syscall numbers), rename OP_COPY_ARGS to OP_LOAD (it loads _selected_ stuff from arguments) As for cooker itself: - drop ARG_ and arg_ prefixes from struct names, and similar - add/rework functions to build OP_NR, OP_LOAD, OP_CMP, and to write constant data to gluten - add parsing for "compound" arguments, but that's not completely hooked into evaluation for numeric arguments yet Signed-off-by: Stefano Brivio --- operations.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'operations.h') diff --git a/operations.h b/operations.h index 3a4caa2..ecb6414 100644 --- a/operations.h +++ b/operations.h @@ -20,6 +20,7 @@ struct arg_clone { }; int do_call(struct arg_clone *c); -int do_operations(void *data, struct op operations[], struct seccomp_notif *req, +int do_operations(struct gluten *g, struct op operations[], + struct seccomp_notif *req, unsigned int n_operations, int notifyfd); #endif /* ACTIONS_H */ -- cgit v1.2.3
